Using hybrid physiological/mensurational modelling to predict site index of Pinus sylvestris L. in Sweden: a pilot study
Precision and bias of a model designed to predict site index of Scots pine (P. sylvestris L.) from site variables in Sweden were tested using data from 1985 inventory plots. The model was biased and relatively imprecise ...
Comparison between meteorological data from the New Zealand National Institute of Water and Atmospheric Research (NIWA) and data from independent meteorological stations
Background Hybrid eco-physiological/mensurational models of forest production generally require monthly meteorological estimates at local points in the landscape as inputs. Where to obtain these estimates and how best to ...
Validation of ultrasonic velocity estimates of wood properties in discs of radiata pine
Background: Measurement of microfibril angle (MFA) in the S2 layer of the cell walls of wood using speed of sound in wood has become a common way to estimate wood stiffness and stability. Measurements across the radius ...
Influence of climate and forest management on damage risk by the pine weevil Hylobius abietis in northern Sweden
The pine weevil Hylobius abietis (L.) is an economically important pest insect that kills high proportions of conifer seedlings in reforestation areas. It is present in conifer forests all over Europe but weevil abundance ...
Using soil-based and physiographic variables to improve stand growth equations in Uruguayan forest plantations
(Italian Society of Sivilculture and Forest Ecology (SISEF), 2019)
Information provided by traditional growth models is an essential input in decision making processes for managing planted forests. They are generally fitted using inventory data guaranteeing robustness and simplicity. The ...
